Chemguard Ultraguard 3% AR-AFFF (CUG) is a specially formulated, aqueous film forming free flowing viscous foam concentrates. It forms a vapor suppressing aqueous film on hydrocarbon type fuels or a polymeric membrane on polar solvent/water miscible type fuels. Ultraguard 3% AR-AFFF is intended for use at a proportioning rate of 3% (3 parts CUG concentrate to 97 parts water) on hydrocarbon fuels such as gasoline, kerosene, diesel, etc., and on polar solvent/water miscible fuels such as alcohols, ketones, esters, etc.
U. L. Listed, Foam Liquid Concentrate.
Type Approval: GB15308-94.
EN-1568-3 (1A) .
Used at a 3% proportioning rate on both hydrocarbon
and polar solvent fuels.
Suitable for use with either fresh or salt water.
Excellent wetting characteristics when used in combating Class A fuel fires.
Suitable for use with deluge and closed head foam water sprinkler systems.
Suitable for use with fiberglass, polyethylene or stainless steel.
Ultraguard 3% AR-AFFF is not compatible with galvanized pipe or fittings in an undiluted form.
Suitable for use with dry chemical extinguishing agents.
Suitable for use with both air-aspirating foam and standard water fog nozzles
Fixed or portable in-line eductors .
In-line balanced pressure and pump pressure proportioning skid .
Bladder tank balanced pressure proportioning systems .
Around the pump proportioners .
Handline, air-aspirating nozzles with fixed eductor pickup tube
Cannot be used in sub-surface applications with polar solvent type fuels.
Aspirating type discharge devices typically generate expansion ratios between 6-10 to 1 when 3% AR-AFFF is mixed with water at the correct ratio. Non-aspirating type devices will typically generate expansion ratios of between 2-4 to 1. Expansion ratios are dictated by the type of discharge device, flow rate and discharge pressure.
